% -------------------------------------------------------------------------
% Finds problematic sets of paramters via checking the necessary rank condition
% of the Jacobians for all possible combinations of parameters. The rank is
% computed via an inbuild function based on the SVD, similar to matlab's
% rank. The idea is that once we have the Jacobian for all parameters, we
% can easily set up Jacobians containing all combinations of parameters by
% picking the relevant columns/elements of the full Jacobian. Then the rank
% of these smaller Jacobians indicates whether this paramter combination is
% identified or not. To speed up computations:
% (1) single parameters are removed from possible higher-order sets,
% (2) for parameters that are collinear, i.e. rank failure for 2 element sets,
% we replace the second parameter by the first one, and then compute
% higher-order combinations [uncommented]
% (3) all lower-order problematic sets are removed from higher-order sets
% by an inbuild function
% (4) we could replace nchoosek by a mex version, e.g. VChooseK
% (https://de.mathworks.com/matlabcentral/fileexchange/26190-vchoosek) as
% nchoosek could be the bottleneck in terms of speed (and memory for models
% with totparam_nbr > 150)
% =========================================================================
% INPUTS
% ide_reducedform: [structure] Containing results from identification
% analysis based on the reduced-form solution (Ratto
% and Iskrev, 2011). If either options_ident.no_identification_reducedform
% or error_indicator.identification_reducedform are 1 then the search for problematic parameter sets will be skipped
% ide_moments: [structure] Containing results from identification
% analysis based on moments (Iskrev, 2010). If either
% options_ident.no_identification_moments or error_indicator.identification_moments are 1 then the search for
% problematic parameter sets will be skipped
% ide_spectrum: [structure] Containing results from identification
% analysis based on the spectrum (Qu and Tkachenko, 2012).
% If either options_ident.no_identification_spectrum or error_indicator.identification_spectrum are 1 then the search for
% problematic parameter sets will be skipped
% ide_minimal: [structure] Containing results from identification
% analysis based on the minimal state space system
% (Komunjer and Ng, 2011). If either options_ident.no_identification_minimal or
% error_indicator.identification_minimal are 1 then the search for problematic parameter sets will be skipped
% totparam_nbr: [integer] number of estimated stderr, corr and model parameters
% numzerotolrank: [double] tolerance level for rank compuations
% error_indicator [structure] indicators whether objects could be computed
% -------------------------------------------------------------------------
% OUTPUTS
% ide_reducedform, ide_moments, ide_spectrum, ide_minimal are augmented by the
% following fields:
% * problpars: [1 by totparam_nbr] cell with the following structure for j=1:totparam_nbr
% problpars{j}: [nonidentified_j_set_parameters_nbr by j]
% matrix with j collinear parameters in each row
% * rank: [integer] rank of Jacobian
% -------------------------------------------------------------------------
% This function is called by
% * identification.analysis.m
